FATAL BUG IN YOUR PERL SETUP DETECTED. BUILD TERMINATED.

On this platform the combination of gcc and the Perl malloc
are buggy. The optimizations lead to random coredumps
and make PDL essentially unusable.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
WORKAROUND: YOU MUST RECOMPILE PERL WITH 'usemymalloc=n' !!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You may override and force the build by including the
'FORCE' switch:

  perl Makefile.PL FORCE

However, you will most likely end up with an unusable
PDL build unless *all* optimizations are disabled!
YOU HAVE BEEN WARNED!!

**********************************************************************
Your Perl \@INC path is:

$INC

That seems to include the directory '.' before the last entry in the
path.  Configurations like that might be broken, because they may
prevent strict division of hierarchy in the module name space.
In particular, adding a module Foo::Bar::Baz can cause trouble
if Baz exists in the top level elsewhere, and if you run from the
Foo/Bar directory.

This happens with the PDL::Config and some other modules.  You may
not be able to build PDL with this \@INC setup.

If you strike trouble, you may need to fix your \@INC.
